I get about 3 calls a day from this number, all hours. It does not have a caller id, nor does it say anonymous or unknown. Once it had V81812360700015 for the id. I have answered this call a number of times as it is a local number for me. No one answers and after a minute it hangs up and the phone starts beeping fast. I am also getting calls from a 972-370-3053 with the same issue. I suspect they are related. I suspect this is a scam for a security system or medical alerts as I have gotten a lot of calls around those lately.
The number is 972-347-4365. Lucas,TX. Just another person with no life except to scam others. If it is on your cell phone, just block it. I have a Verizon Fios land line, so I just log onto my account and go to "call block", type in the phone number and add it to my list. That is the end of them. :-)
